Description

cooling module

The present invention relates to a cooling module in which a plurality of heat exchangers are stacked and combined for cooling an automobile engine and cooling an air conditioner refrigerant.

Generally, the cooling module is mounted on the front end module carrier at the front of the vehicle to cool the car's engine and air conditioner refrigerant. The condenser and radiator are stacked side by side with a certain distance apart, and a fan shroud assembly is formed on one side of the radiator to cool the vehicle. During the process, it is formed into a structure that causes heat exchange in the condenser and radiator by the flow of air or the driving of the cooling fan.

Figure 1 is a schematic diagram showing a conventional cooling module.

For example, in a conventional cooling module, as shown in FIG. 1, a condenser 30, a second radiator 21, a first radiator 11, and a fan shroud 40 are arranged side by side from upstream to downstream in the direction of air flow. It may be configured in a stacked arrangement. Here, the first radiator 11 may be an engine radiator for cooling the engine, and the second radiator 21 may be an electrical radiator for cooling electrical components. In addition, although not shown, an oil cooler for cooling the transmission oil may be disposed on the upstream side of the condenser 30.

Recently, for engines that require high heat dissipation performance, cooling performance may be insufficient with just one engine radiator, so cooling performance can be increased by connecting an additional auxiliary radiator.

However, since the conventional engine radiator has only one inlet port and one outlet port connected to the engine, an additional structure is required to connect the engine radiator to a separate auxiliary radiator.

The fan shroud can drive a fan to force the cooling air to pass through the heat exchangers. Additionally, a third radiator, which is an auxiliary radiator, may be installed at a location that does not overlap the engine radiator 100, full-length radiator 200, condenser 300, and oil cooler 400 in the direction of cooling air flow. That is, the third radiator is not disposed on the flow path of the cooling air passing through the engine radiator 100, the full-length radiator 200, the condenser 300, and the oil cooler 400, and the third radiator is spaced apart from them. It can be placed in a location. Additionally, a third radiator may be separately installed outside the assembly in which the engine radiator 100, the full-length radiator 200, the condenser 300, and the oil cooler 400 are combined.

Here, the engine radiator 100 may include a pair of header tanks 110 and a plurality of tubes 120, and may further include a plurality of fins 130. The pair of header tanks 110 may be arranged side by side and spaced apart in the longitudinal direction, and the plurality of tubes 120 may be connected to the pair of header tanks 110 at both ends to communicate. And as an example, one of the pair of header tanks 110 may have a main inlet port 111 through which coolant flows, and a main discharge port 112 through which coolant flows out may be formed in the other header tank. there is. Additionally, an auxiliary discharge port 113 may be formed in the header tank in which the main inlet port 111 is formed, and an auxiliary inlet port 114 may be formed in the header tank in which the main discharge port 112 is formed.

If they are spaced apart from each other in the longitudinal direction of the header tank or are formed on different header tanks, they may flow to the auxiliary radiator after some heat exchange in the engine radiator 100, which may be detrimental to the heat exchange performance of the auxiliary radiator. And the main inlet port 111 and the auxiliary discharge port 113 are adjacent to each other and are located on the upper side in the direction of gravity, so that they can easily flow by gravity.

Additionally, the auxiliary inlet port 114 and the auxiliary discharge port 113 may be formed in a shape that expands outward in the longitudinal direction toward the upstream side in the flow direction of cooling air in the engine radiator 100. Therefore, the auxiliary inlet port 114 and auxiliary discharge port 113 interfere with the full-length radiator 200, condenser 300, and oil cooler 400 disposed upstream of the engine radiator 100 in the direction of cooling air flow. You can prevent it from happening. In addition, not only can interference be avoided, but the piping connected to the auxiliary discharge port 113 and auxiliary inlet port 114 of the third radiator and the engine radiator is less bent, so that the length of the connecting pipe is reduced compared to when it is bent a lot.

In addition, the auxiliary discharge port 113 and the auxiliary inlet port 114 may be formed to protrude in the longitudinal direction from the header tank 110, respectively. As shown, a protrusion 116 is formed in the longitudinal direction of the header tank 110 based on the outer surface of the header tank 110 in the longitudinal direction of the engine radiator 100, and an auxiliary discharge port is formed at the protrusion 116. (113) and the auxiliary inlet port 114 may be formed in an extended form. Therefore, it is possible to prevent the auxiliary inlet port 114 and auxiliary discharge port 113 from interfering with the full-length radiator 200, condenser 300, and oil cooler 400 disposed upstream of the engine radiator 100. .

In addition, the auxiliary discharge port 113 or auxiliary inlet port 114 is connected to the refrigerant inlet pipe 310 of the condenser 300 at a position corresponding to the refrigerant inlet pipe 310 and the refrigerant outlet pipe 320 of the condenser 300. and may be disposed longitudinally outside the refrigerant outlet pipe 320. Thus, it is possible to prevent the auxiliary inlet port 114 and the auxiliary discharge port 113 from interfering with the refrigerant inlet pipe 310 and the refrigerant outlet pipe 320 of the condenser 300.

Likewise, the auxiliary discharge port 113 or auxiliary inlet port 114 is located at a position corresponding to the oil inlet pipe 410 and the oil outlet pipe 420 of the oil cooler 400. ) and may be arranged longitudinally outside the oil outlet pipe 420. Thus, it is possible to prevent the auxiliary inlet port 114 and the auxiliary discharge port 113 from interfering with the oil inlet pipe 410 and the oil outlet pipe 420 of the oil cooler 400.

Additionally, the auxiliary discharge port 113 may be placed adjacent to the main inlet port 111. Therefore, the coolant flowing into the header tank 110 through the main inlet port 111 can easily flow not only through the plurality of tubes 120 but also into a separate auxiliary radiator through the auxiliary discharge port 113.

In addition, the full-length radiator 200 has an inlet pipe 210 and an outlet pipe 220 extending toward the downstream side in the flow direction of the cooling air, and is connected to any of the pair of header tanks 110 of the engine radiator 100. At least one concave insertion groove 115 is formed, and the inlet pipe 210 and the outlet pipe 220 of the full-length radiator 200 can be inserted and disposed in the insertion groove 115.
